SL55/63/65/R230 AMG: SL55 ECM
i followed all the advise here step by step.
I swapped a ECU from my 2003 into my 2006 as was suggusted. The fan operated fine. I sent my ECU to Pressortech to be tested and if possible repaired. I changed the coolant temp sensor, A/C pressure sensor, and other relays before sending it out. I will post the results thanks for the help.
P.S I cannot drive my 2006 Sl55 because it got keyed and the hood is at the shop. The Sl500 is awaiting a new fuel disturber. Now I have to drive around in my truck in this nice Florida weather.
